IMAP errors

I'm using PHP's IMAP functions, and they seem to be working fine, 
however, on the page where I call imap_fetchstructure() I get a string 
of errors at the very end of the script. they do not occur at the point 
the function is executed, rather at the very end.

They do not specify where they actually occur, and I don't know what 
actually causes them. Can anyone shed some light on this for me? Here 
are the errors:

<p>
